GANGr-PLOW.

To all wiiom it may concern:

Be it known that I, VVILLIAM N. SPRINGER,

' plow units,the object of my invention being to provide simple and eflicient manually operable means whereby the accurate operation of the raising means and their release to permit the lowering of the plow units, may be insured. l

A furthenobject is to so construct raisingand lowering mechanism for the plow units of a gang plow, that each plow unit may have such mechanism carried thereby, and so-that the-manually operable controlling means for" the mechanisms on the several plow.units,'. may be mounted upon the truck frame and operatively connected with the raising'and lowering mechanisms in' such manner as-to effect-the operation of the same;

With these and other objects in view, the

inventionconsists in certain novel features of construction and combinationsof parts; as hereinafter set forth and pointed out n the claims.

In the accompanying drawings; Figure '1 is a side elevation of a portionz of a plow arel' detail views showing the; latch devices for the arm :27;I and F1Q, 6' is an enlarged detailviewof the arm 2'1 and segment .30.

duplicates of each other, detail description of one will sufiice for all.-

Each plow unit comprises two members spaced apart and held rigid with respect to each other by means of a transverse bracket or spacer 5 located intermediate ofthe ends of said beammembers and securely bolted to the latter. The beam member 3 is straight from end to end, while the rear portion of the beam memberv 41: is bent toward the beam member 3 and liesparallel with the latter, so-th'at the rear portions of the beam'members will be properly spaced lapart to receive the upper portion of aplow standard 6 and connecting means therefor,

said plow standard being secured at its lower end to the soil-engaging member 7.

'lhefor'ward ends of the beam members 3-4 are connected by a bracket S, and the latter isprovided with forwardly projectof the respective beam membersand the guideways of these brackets are slightly in- "clined forwardly td receive forwardly inclined-standards'l7. {The lower ends 'ofj-the standards fl are connected by the" axle of a gagehor lifting wheel 18, and the upper endsf'of said-standards are connected by. a

frame. on bracket '19,. which projects forwardly. froin'the same,

,securely'boltedf to the beam member 4 nearthej 'rear'end of the latter and project- 'ing above the same, is a bracket 20 provided "atits upper forward end with laterally projecting bosses 21 to receive bosses '21 on the two members of a triangular arm 21- and form pivotal supports for the latter. The two, sections of the arm 21 embrace the lower end of a lifting lever 22, which is secured connected with arms 26 secured to the lower ends of the standards adjacent to the axle of the gage or lifting wheel 18. It is apparentthat if thelever-22 bemoved downwardly, the rear ends of the beam and the soil-engaging member will "be raised, the guides 16 on the beam members moving upwardlyon the standards 17, and that when said lever is raised, 'theplow beam and soilengaging member will be lowered.

An arm 27 is pivotally mounted between its ends, upon the boss 21 of one of the sections of' the'arm' 21, and in' this manner,

' said arm 27 is supported by the bracket 20,

with its pivotal supportin line with that of the11over22. One end, of the arm 27 is made with a head 28 having a recess 29 in I one face, and the other cnd'of said arm is made with a toothed segment 30. The

' head'28 at-thesmaller end of the segment arm 27 enters a slotted enlargement 31 at the rear end of thc.bracket 20, and is normallyheld in said enlargement by" means of a latch 32,'the latter being pivotally supported on the bracket 20 at its. upper end and adapted to enter the recess 29 in ;.the head 28 of said' latch arm. The lower portion'of the enlargement 31 is' made with a transverse hole 33 for the passage of'a bolt 34 attached-t0 the lower end of the'lat'ch, and a portion of the'l10le-'33"is enlarged for the reception of a spring 35 which bears at one end against a suitable nut on the free endof the bolt 34 and thusserves to yield ably hold the latch in place when the head 28 of thesegment arm is engaged thereby.

A latch 36 is pivoted-at one end to the triangular-arm 21 and provided- "with a suitable-tooth which is pressed into engage-- v ment with the segment 30, by means of a spring 37, and to the free end of the latch, an operating rod 38 is attached.

A spring 39 may be attached at one end to the lifting'levcr 22 and at the other end to the plow standard or to'the rear portion of. the beam, to assist in the operation of raising the plow when the lifting lcver 22 is depressed. The frame IQ-secured to the upper ends of the standards 17, is provided with bearings for a shaft 40, to which a sprocket wheel 41 is secured. A larger sprocket wheel 42 is secured to the hub of t 1 e gage or lifting wheel 18 and transmits motion, through the medium of a sprocket chain 43, to the sprocket wheel 41 on the shaft 40. The sprocket 41 is provided with clutch teeth 44 to cooperate with clutch teeth 45 on one end of a drum or hub 46 mounted loosely on the shaft 40.. The drum or hub 46, whichconstitutes the movable member of the clutch, is provided at one end with an annular flange 47, which also forms one flange for a sleeve 48 movable with the drum 46. The sleeve 48 is made with an annular enlargement 49,. and at one side of the latter, an annular flange '50 is formed of the chain 53 with said lever.

and provided with a cam 51 projecting laterally over the peripheral portion of the annular enlargement 49. The sleeve 48 is recessed for the accommodation of a spring 52, one end of which is seated in said recess and the other end of whlch bears against theframe 19, said spring tending to force the sleeve and the clutch member carried thereby, into operative relation to the clutch "member-onxthe sprocket 41.

A chain 53 isatt ached atone end to the drum '46 and adapted to wind upon the latter, the other end of said chain being connected with the lifting lever 22, through the medium of a hook 5 4. The hook 54 is bifurcated so as to embrace the leverr22 and the uppcrends of the two arms of the hook are pivotally attached to alink 55,'onc end of which latter is pivotallyattached to an arm 56 secured to the lever 22. An adjusting screw 5? passes through vthe link 55 (preferably near the free end of the latter) and-engages the lever 22, whereby the link 55'may be adjusted to adjust the connection A plate 58 -is secured over theforward end of. this plate, one end of an arm 59 is pivotally supported at 59 and disposed under said plate. Nearits free end, the arm- 59 carries a roller 60'to cooperate with the annular enlargement 49 andcam 51 of sleeve 48, as'hcreinafter explained. At the other end ofthe plate 58, one end of a lever 61 is pivotally attached at 61 the other end' of said lever projecting laterally beyond the opposite side of the frame 19 and connected with the rear end ofthelatter through the medium of aspiring 62, the rear end of the frame 19 being provided with hooked arm 63to receive said spring, The lever 61 is provided between its ends with an elongated slot 64 for the accommodation of a pin 65vsecured to the pivoted arm 59, said pin also passing through an elongated slot slot. 64 in the sleeve 61) in the plate 58.

66 (approximately at rightangles to the hen the parts are in thepositions shown A in 3, the roller'60 is inengagement with the side face of the annular enlargement 49 andeis holding the clutch member's separated. Should the lever. 61- be moved ferwardly, the pivoted arm 59 with which said lever is connected, would also be-moved forwardly and. the roller 60 moved out of engagement with the side of enlargement 49, such movement of the pivoted-arm and roller beingguided and limited by the move izo ments of the pin 65 in-the elongated slots 64 and 66. l/Vheri'thc roller 60 shall have been moved as above described, the'sleeve' 48 will be free to be slid on the shaft 40 by the actionof the spring 52 for-engaging the clutch teeth 45 with theclutch teeth-44.

' In other word s,the spring 52*Will bjfi'ee to act in moving the sleeve 48 to close the clutch.

Motion will now be imparted to the :cl1'-um'.46:'towind thechain 22 thereon for effectingthellowering of the lifting lever 22 andthe consequent raising of, the plow beam and soil-engaging member, which operations will continue nntilthe roller 60 p is engaged the cam 51 to disengage the clutch teeth; During these operations the lever 22 will be locked .to the segment arm 27 and thel lattcr will bereleased, from the spring pressed latch m the slotted en,- largment 31, and move,',w1th sa d lever.-

When the parts are permitted to again as ,snme their normal positions. with the plowlowerechthe segment arm 27 will be locked automatically llhen the lifting lever 22 shall have been depressed to raise the plow as hereinbefore 1 described by the aimlication' of power from the wheel 18, it will be held in such position by the'engagcment of a hook 67 with a bolt 68 on the lever 22. The hook 67 is pivotally ino nnted upon' a pedestal 69 located on the spreader 5 and is limited 1n one direction by a foot 70. A lug 71 projects forwardly from the hook andbetween this lug and a--.snpport on thepedestal. a spring 72 is disposed to retain the hook in and re- .turn it to its normal position.- The hook 6'1 is bifurcated. to embra'cethe lever 22 when the latter is lowered, and they members of said hook are provided at'their upper ends with beveled or cam projections 78 to engage the bolt 68 on the/lever and cause the hook to snap over the same.

As'hereinbefore' stated, each plow unit is provided with the'lifting devices such as above described in detail. and devices may be provided forcausing the 'inechanisms-on the several plow units to be operated to effect the raising of the plows or to drop them, -.Thus, two levers 74-75 may be 'pivotallysupported'lrat or near one end by a.

bracket 76 secured upon'the beam 1 of the truck frame. 'lll e lever 7 5 is connected by means of an adjustable rod 77 with the free end ofthe clutch lever 61, and the lever X4 is connected by means of an adjustable rod 78 with the hook 67.

A bar 88 may be'mounted to slide through the brackets 76' on the truckframe and this bar may be p'rovidedwith cam blocks 93, 94,- fos operatin the levers 74 and to pull the rods 7 8 and 7? for controlling the operation ofthe raising and lowering mechanism.

Let it be assumed that all the plows are in workingposition, with the mechanism of each jplow unit disposed as shown in Figs. 1 and 2, and that it is desired to raise the plows. The operator will move the. slide bar longitudinally and cause the cam block 94 to actuate the-lever 7 5, thus causing the latter to be turned on its fulcrum and imthe plow shall havefbeenithus-raised, the

by the operation of the part motion-through rod .77 tothe'clutch lever 61.0fa plow unit,the.movem"ent. of said clutch lever acting to release the mov able clutch member and permit the teeth 45 to engage the clutch teeth 4Abnsprocket' wheel il. T he chain 53-will be wound upon the druin lti by power from'the "wheel '=18,

as hereinbefore explainedsand the lever 22 will be lowered to raise the plow. W'hen lever willjbe retained ii -its lowered positionpby the hooks 67, and the clutch will beautomatically opened as previously 1 ex, plained. I

When it, is desired to release the levers 22 to permit the plows to drop to workingpositions, the, operator-willmove the slide bar 88 in the reverse direction, whereupon the cams 93 will operate the levers 74, and thus cause motion to be imparted through the. rods 78 to the hooks 67 "to withdraw-the same'from v engagement with the levers 22,

permitting the latter to rise and the plows to drop to working position, A l 4 Various changes might be made ln-the de.
